` Application and Jnlyzv, 1903. semina. 167,113. ca model.)

To all 'whom i315 may concern: Be it known that I,- ARTHUR C. BADG'ER, of.

tainty of operation, reduction ofwear, and.

kindred advantages.

The lnvention as carried outin the embodiment illustrated is applied to a device knownas a compression-cock, and includesa valve casing and seating valve therein having a threaded body or stem'V engaging the casing for producing. an axial opening and closing movement of the valve when the latter is rotated. Straddling the casing is a bowed operating-handle within easy reach ofthe iinygers of an operators hand holding the valvecasing, Aone end of this handle being iixed to the valve-stem torotate-the same and movable axially therewith, while the opposite end of the vhandle has a sliding bearing onthe' casing opposite the projecting valve-stem.

0f the accompanying drawings* Figure 1 represents a side elevation ofA a stop-valvel mechanism constructed according to the pres ent invention with thevalve closed. .'Fig. -2

represents an end' elevation. Fig. 3 represents an elevation at right angles to Fig. `1.

Fig. 4 represents a'longitudinal section showing the valve op n. Fig. 5 represents a trans- Y verse section sh wing the valveclosed. Fig.

6 represents a transverse section showing a modification.

with an aperture surrounded by a valve-seat- 141s the rotatable and axially-movablev 13. valve adapted to open land close against' said seat and having its stem or body formed with a quick-pitch screw-thread 15, engaging a com-pleniental thread' 16., formed within a branch oi. the casing, which is closed by a screw-cap 17. The reduced part`18 of the valve-stem passes through a stuiing-box 19 in this cap and outside of the casing is formed with a polygonal or Hat-sided portion 20, with which is connected one end ot' a bowed operating handle or bail 21, straddling the casing. A rigid connection` between the valve-stem and the handle isi-thus formed, whereby when the handle is rotated or. oscillated by the operators fingers the valve is also rotatedbecause of the screw-thread `and causedfto 'open and close against' its seat by an`aX-ial movement.v The opposite end otthe handle 21 is provided with a bearing on acylindrical stud 22, screwed on an integral stem 23, which is forrried 0n the casing in line with the axis of the valve. This end of the handle is mounted for an axial sliding movement on the stud 22, which permits the'axialmoveand'closing movement of the valve. lIt will -be observed that the' handle 21 -is brought within convenient reach of the thuinb or. tingers of the operators hand holding the valvecasing 10, so that this form of apparatus permits the operator -to handle and direct the valve-casing and operate the valvethere'of with one hand. At the same time they handle 1 is adequately supported, giving an easy move- -rnent thereofl with a minimum oi" friction and reducing wear and strain on the'valve andits stem 'and because of such construction permitting the parts to .be made relatively light without sacrificing strength or, durability:

Modifications may be made without departing from the idea of means contained in the. described construction. For instance, the location of thescrew-thread may be changedor equivalent devices giving the same effect may be substituted therefor. In Fig. 6, for example, I have show'n the valve-stem as having a smooth bearing24= within the casing 'and the` studl 22and. operating-handle l21 as having complemental threads 25 26 formed thereonfor producing thedesired 'axial movement of a stem projecting outside the casing, and a bail straddling the casing, one of its ends having a bearing on the casing opposite the pro- IOO jecting stem, the other end being engaged with the stern., and means whereby arotary movement of said bail imparts an axial movement` to the valve. y

2. In a stop-valve mechanism, a casing, a seating valve therein opening and closing by an axial movement, cooperating threaded members on the valve structure and 'casing respectively for producing suchmovement by their relative rotation, and a bail for producing such relative rotation, the same straddling the casing and having one end connected to the valve structure, its other end having a bearing on the opposite side of the casing from'A such point of connection.

3. 1n a stop-valve mechanism, a valve-casing, a rotatable and axially-movable operat' connected with the other end of the handle for operation thereby. n

4. ln a stop-valve mechanism, a casing, a

- valve therein opening and closing by an axial movement, cooperating screw-threaded meinbers for producing. said axial movement, one of which has a projection outside of the casing, and an axially-movable bail having one end connected to rotate said projection and move axially therewith, the other end having a sliding bearing on the casing opposite said projection. l

In. testimony whereof I have affixed my sig nature in presence of two Witnesses.
